DETAILED DESCRIPTION

Embodiments of the present application are described in detail below, and examples of the embodiments are illustrated in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar modules or modules having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, are only intended to illustrate the present disclosure, and are not construed to limit the present disclosure. Rather, embodiments of the present application include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

In related arts, the generally displayed navigation information is a distance from the intersection for changing direction to a current position, such that the driver may makes a judgment based on the distance. However, it is difficult for the driver to identify the distance. For example, it is difficult to distinguish between 200 meters and 150 meters. As a result, it is impossible to quickly and accurately find the intersection for changing direction guided by the navigation, and thus entering a wrong way occurs.

Therefore, embodiments of the present disclosure provide a method and a device for displaying navigation information, a locating device, a non-transitory computer readable storage medium, and a computer program product.

FIG. 1 is a flow chart illustrating a method for displaying navigation information provided in embodiment of the present disclosure.

As illustrated in FIG. 1, the method according to embodiments of the present disclosure includes the following.

In block S11, a current position and a position of an intersection for changing direction are acquired.

The current position (denoted by CurPos) may be acquired according to a global positioning system (GPS), and the position of a next intersection for changing direction (denoted by GuidePos) may be acquired according to a route planning. The term “intersection” refers to a next marked position of a navigation route, which may be a positon for changing the direction, or may be a position that is a fork instead of changing direction.

In block S12, road features between the current position and the position of the intersection for changing direction are analyzed to determine a ground object of the intersection for changing direction.

The ground object of the intersection for changing direction refers to a certain feature of the intersection, such as a traffic-light intersection, a regular crossing intersection, being at an end of a road, or the like. Generally, the ground object is easily identified by a user.

In detail, the ground object may be defined by analyzing whether the road features between the current position and the position of the intersection for changing direction satisfy defined ground objects and satisfy which kind of the defined ground objects. Therefore, the ground object of the intersection for changing direction may be determined.

The ground object of the intersection for changing direction may include at least one of the followings illustrated in Table 1.

In block S13, the ground object of the intersection for changing direction is displayed.

When the ground object of the intersection for changing direction is determined, the ground object may be used as a kind of navigation information, such that the ground object may be displayed to the user together with other navigation information.

For example, as illustrated in FIG. 2, at a left side, there is a schematic diagram for conventionally displaying the navigation information. The navigation information includes a turning type pattern 21, a distance 22 from the position of the intersection for changing direction to the current position, and other information 23 of the intersection for changing direction. In comparison, in embodiments of the present disclosure, as illustrated at a right side of FIG. 2, the navigation information further includes the ground object 24, in addition to conventionally displayed information.

In embodiments, by determining and displaying the ground object of the intersection for changing direction, it allows the user to quickly and accurately find the intersection for changing direction guided by navigation, since the ground object is easily identified by the user, thereby improving user experience.

FIG. 3 is a flow chart illustrating a method for displaying navigation information according to another embodiment of the present disclosure.

As illustrated in FIG. 3, the method according to embodiments may include the following.

In block S31, a current position and a position of an intersection for changing direction are acquired.

The current position (denoted by Curpos) may be acquired based on a GPS, and the position of the intersection for changing direction (denoted by GuidePos) may be acquired according to a route planning.

In block S32, road features between the current position and the position of the intersection for changing direction are analyzed to determine whether there is a ground object of the intersection for changing direction. When there is the ground object of the intersection for changing direction, a block S34 is executed. Otherwise, a block S33 is executed.

The ground object of the intersection for changing direction refers to a certain feature of the intersection for changing direction, such as a traffic-light intersection, a regular crossing intersection, being at an end of a road, or the like.

In detail, the ground object may be defined by analyzing whether the road features between the current position and the position of the intersection for changing direction satisfy defined ground objects. When there is a road feature satisfying the defined ground objects, it is determined that there is the ground object of the intersection for changing direction. Otherwise, there is no ground object of the intersection for changing direction.

In block S33, conventional navigation information is displayed.

For example, the navigation information illustrated at a left side of FIG. 2 is displayed, including a turning type pattern, a distance from the position of the intersection for changing direction to the current position, a name of the intersection for changing direction, or the like.

In block S34, the ground object of the intersection for changing direction is determined.

By analyzing whether the road features between the current position and the position of the intersection for changing direction satisfy the defined ground objects, a road feature satisfying the defined ground objects is determined as the ground object of the intersection for changing direction when there is the road feature satisfying the defined ground objects.

In block S53, when there are a plurality of ground objects of the intersection for changing direction, a ground object having a highest priority level is selected from the plurality of ground objects according to priority levels of the plurality of ground objects.

The priority level for each ground object may be set in advance. For example, the priority levels of the plurality of ground objects may be defined as: the priority level of “an end of a road”> the priority level of “traffic light”> the priority level of “bridge”> the priority level of “tunnel”> the priority level of “crossing intersection”> the priority level of “second intersection”.

Therefore, the ground object having the highest priority level may be selected from the plurality of determined ground objects, according to a relation of the priority levels set in advance.

In block S36, the selected ground object of the intersection for changing direction is displayed.

For example, ground objects of an intersection between the current position and the position of the intersection for changing direction are analyzed. The ground objects of the intersection include: an end of a road and a traffic light. Since the priority level of “the end of the road” is higher than the priority level of “the traffic light”, “the end of the road” is selected and displayed as the navigation information.

Further, when the ground object of the intersection for changing direction is displayed, the ground object may be displayed on a navigation panel in text, as illustrated in FIG. 2. Alternatively, the ground object of the intersection for changing direction may be played in voice for the user.

When a location of the user (such as a driver) is changed, the block S31 and its subsequent blocks may be repeated.

In embodiments, by determining and displaying the ground object of the intersection for changing direction, it facilitates the user to quickly and accurately find the intersection for changing direction guided by navigation, since the ground object is easily identified by the user, thereby improving user experience. Furthermore, when there are a plurality of ground objects, the ground object having the highest priority level selected from the plurality of ground objects may be displayed according to the priority levels of the plurality of ground objects, such that a display effect is improved. Further, when there is no ground object, the conventional navigation information is displayed, which may be compatible to related arts.

The selecting module 44 is configured to select a ground object having a highest priority level from the plurality of ground objects based on priority levels of the plurality of ground objects, to display the selected ground object.

In some embodiments, the ground object includes at least one of: a traffic-light intersection, a crossing intersection, a second traffic-light intersection, a second crossing intersection, a second intersection, an end of a road, being in a tunnel, a preset distance or a next intersection after a bridge, a preset distance or a next intersection after a tunnel, a preset distance or a next intersection after a traffic-light intersection, a preset distance or a next intersection after a crossing intersection.

In some embodiments, as illustrated in FIG. 5, the device 40 further includes a second displaying module 45.

The second displaying module 45 is configured to display conventional navigation information when there is no ground object of the intersection for changing direction.

It may be understood that, by determining and displaying the ground object of the intersection for changing direction, it facilitates a user to quickly and accurately find the intersection for changing direction guided by navigation since the ground object is easily identified by the user, thereby improving user experience.
